"No worries" is a common idiom, particularly in Australian English, used as a versatile expression similar to phrases like:

• "You're welcome" or "That's okay" after someone expresses gratitude. See: https://www.wikiwhat.page/kavramlar/You're%20Welcome
• "Don't worry about it" or "It's not a problem" when acknowledging an apology or excusing a mistake. See: https://www.wikiwhat.page/kavramlar/Don't%20Worry%20About%20It
• A general expression of reassurance or encouragement to alleviate anxiety.

Its usage often implies a sense of laid-back acceptance and lack of concern. It is not exclusive to Australia, however, but its widespread use there has made it a cultural identifier. The phrase has gained popularity globally through exposure in media and travel.
